It is the Divinity engine people. This engine cannot and will never be capable of RTWP. Get over it. It is the engine they are using and it is a turn based engine. Please stop suggesting this that the game engine cannot do. This also goes for the 6 man party. This engine cannot do 6 man parties. It is a limitation of the engine and no amount of whinning about it will change it.
If there were limitations in the engine, as you describe - Divinity II modders wouldn't be able to change those aspects of the game. Divinity II there are mods to increase the party size, and there are mods to change from turn-based to real-time combat. Dreygor is right, there are no such limitations.
dang there are? that might actually save the game for me modders are a godsend
